Dr Gabriela Toledo-Ortiz

Lecturer in Plant Science

Research Overview

Gabriela is a Plant Molecular Photobiologist interested in understanding the fundamental mechanisms that allow plants to adapt their growth and development to changing environments.

In particular Gabriela has focused in characterizing the molecular components that integrate light and temperature signals for the control of photosynthesis.
